Recompressor units: For the recompression of bio-methane / natural gas in a higher-grade grid

Indirectly connected to bio-methane production, this application is the ideal system for seasonal balancing of fluctuations in transport and grid overloads.

Should a low-pressure line become overloaded (due to repeated bio-methane infeed, for example), excess natural gas / bio-methane mixture can be fed into a higher-grade grid.

This enables better use to be made of buffer volumes in high-pressure transport systems.

CFS DUO series for the recompression of bio-methane / natural gas

This series has been developed and successfully introduced specifically for the recompression of natural gas (natural gas / bio-methane mixtures).

It is characterised in particular by its variable output pressure which can be adapted to a given grid pressure. The typical scope of delivery of a recompressor unit essentially comprises the compressor (recompressor), its electrical control system and the requisite high-pressure system.

The basic version of the CFS DUO is designed for operation with one compressor (DUO I). If the delivery quantity of bio-methane increases, a second compressor can easily be added to the system (DUO II).

High-pressure gas treatment system
The high-pressure gas treatment system (high-pressure filter) is installed downstream of the compressor on the pressure side. Its primary function is to effectively remove excess moisture and possible oil deposits from the natural gas. Read more

Sound insulation and weather protection
The entire unit is integrated inside a housing made from concrete or steel for sound insulation and weather protection.
This provides the best possible protection against the most extreme ambient conditions and, thanks to the use of air handling units or heating systems, can be used in temperature ranges of ±55°C.
Tailored to meet your individual needs, our housings can be fitted with additional important options such as protection against sandstorms.
